Wireless

Keep in mind that unless you have the best conditions for wireless N, fast ethernet is still faster in file transfers. All of the current and recent ReadyNAS units have gigabit ethernet NICs or better (some rack mount high end units have 10gigabit NICs. The only restriction that wired ethernet puts on the NAS is that it must be reasonably close to a ethernet port. If your home is like mine (not wired), then it needs to be fairly close to the router or switch. In my case on the same side of the room with the router and switch, but accessible in all rooms via the wireless router.

Using a test file that is a .wmv file of 3GB, my file transfer rate to my laptop using wireless 'n' is 5-6 Megabytes per second (MB/s) whereas over the wired gigabit network it is 60-75 MB/s when copied to my desktop. Wireless is great for mobility but terrible for file transfer speeds. For small files, it is not that significant but with data capacity on the NAS units now in double digit Terrabytes, it just doesn't make sense to connect them wirelessly.
